JMGACD-12L is a military/aerospace high-performance relay designed for demanding applications requiring reliable switching and signal control. It features a 12 VDC coil with 390 O resistance and 369 mW power rating, equipped with a coil suppression diode for protection against voltage spikes. The relay employs a 2 Form C (DPDT) contact arrangement with a 1 A contact current rating, housed in a hermetically sealed TO-5/100 grid package with long lead termination for printed circuit board mounting. Operating across a wide temperature range of -65°C to +125°C, the relay demonstrates exceptional environmental robustness with 30G vibration tolerance (10–3000 Hz) and 75G shock resistance (6 ms), making it suitable for aerospace, military, and other high-reliability applications where hermetic sealing and performance stability are critical.
